--src option erroneously filled

If you don't pass an --src option, it is filled nevertheless if you give 
arguments of the command line.  It happens in the code part

for attr in missing_reqs:
    value = config.lazy_get(service_header, attr)
    if not value:
      if args:
        value = args.pop(0)
      else:
        value = raw_input('Please specify ' + attr + ': ')
    setattr(options, attr, value)

in the routine fill_out_options.  Before these lines, options.src is None, and 
after that, it is the text of the appointment I'd like to add.  The command 
line to reproduce is

/usr/bin/google calendar add "--date=2013-03-27 @ 10:00" --cal=org 
--reminder=10m "phone conference"
